目的探寻临床肝病常用血清生化指标与慢性乙肝患者肝细胞炎症的相关性,以期寻找无创伤性评价肝炎病变程度的方法。方法选择128例慢性乙肝患者,检测其丙氨酸氨基转移酶(ALT)、碱性磷酸酶(ALP)、谷氨酰转肽酶(GGT)、天门冬氨酸氨基转移酶(AST)、白蛋白(ALB)和凝血酶原活动度(PTA),并将其结果与肝炎病理分级进行对比分析。结果 AST、ALT、PTA在不同病理分级(炎症)之间均有统计学差异(P均〈0.05),且随着肝细胞炎症程度加重数值增大;ALB在不同病理分级(炎症)之间均有统计学差异(P〈0.01),随着肝细胞炎症程度加重数值减小;ALP和GGT在不同病理分级之间无统计学差别。结论 ALT、AST、ALB、PTA能反映慢性乙肝肝细胞的炎症程度。 相似文献

慢性病毒性肝炎肝脏病理组织学改变与内毒素检测的关系 总被引:2,自引:1,他引:1
慢性病毒性肝炎患者血中所检测到的内毒素,大多认为是慢性病毒性肝病网状内皮系统功能降低或病理结构改变而致。本文通过对61例有肝组织学诊断的慢性病毒性肝炎患者同期进行内毒素水平的定量检测,对其病理分型、炎症活动度及纤维化程度与内毒素的关系进行了分析。 1 资料与方法 1.1 病例选择 61例慢性病毒性肝炎均为本院住院患者,年龄为14~52(35.6±11.7)岁。男性52例,女性9例。其中 相似文献

Influence of iron on the severity of hepatic fibrosis in patients with chronic hepatitis C 总被引:1,自引:0,他引:1
Lin TJ Liao LY Lin SY Lin CL Chang TA 《World journal of gastroenterology : WJG》2006,12(30):4897-4901
AIM: To evaluate the association among hepatic fibrosis, serum iron indices, and hepatic iron stores in patients with Chronic Hepatitis C (CMC). METHODS: Thirty-two CHC patients were included in our study. The histological degree of fibrosis and inflammation activity was assessed according to the Metavir system. The serum iron indices including ferritin, iron and transferrin saturation were measured. Hepatic iron deposition was graded by Perls' stain. RESULTS: The CHC patients with severe hepatic fibrosis (n = 16) were significantly older than CHC patients with mild fibrosis (n = 16) (P = 0.024). The serum iron indices, increased serum iron store and positive hepatic iron stain were not significantly different between the two groups. In multivariate logistic regression analysis, the age at biopsy was an independent predictor of severe hepatic fibrosis (Odds ratio = 1.312; P = 0.035). The positive hepatic iron stain was significantly associated with the values of alanine aminotransferase (ALT) (P = 0.017), ferritin (P = 0.008), serum iron (P - 0.019) and transferrin saturation (P = 0.003). The ferritin level showed significant correlation with the value of ALT (r = 0.531; P = 0.003), iron (r = 0.467; P = 0.011) and transferrin saturation (r = 0.556; P = 0.002). CONCLUSION: Our findings suggest that the severity of hepatitis C virus (HCV)-related liver injury is associated with patient age at biopsy. Both serum iron indices and hepatic iron deposition show correlation with serum indices of chronic liver disease but are not related to grade and stage of liver histology. 相似文献

Background The aim of this study was to assess the diagnostic performances of liver stiffness measurement (LSM), ultrasonography (US)
and their combined use in predicting the extent of hepatic fibrosis.
Methods Consecutive patients with chronic hepatitis B (HBV) or hepatitis C virus (HCV) infections, with indications for liver biopsy,
were prospectively enrolled. LSM was performed on the same day as biopsy. US scores, including assessment of liver surface,
liver parenchyma, intrahepatic vessels and spleen index, were used to assess the degree of hepatic fibrosis. The pathological
findings were used as a reference standard and diagnostic accuracy was assessed and compared.
Results Three-hundred and twenty patients, including 199 men and 121 women, with a mean age of 50.8 years, were analyzed. There were
214 (66.9%) HCV patients, 88 (27.5%) HBV patients and 18 (5.6%) patients with both HCV and HBV. LSM correlated significantly
with the hepatic fibrosis (F) scores, necro-inflammatory activity and US scores in multivariate analysis. The diagnostic accuracy
of LSM is significantly superior to US, and equal to combined LSM with US, in the prediction of all HCV-related fibrosis scores.
The cut-off value of LSM is 6 kPa for diagnosing F > =1, with a positive predictive value of 91%. Also, the cut-off value
is 12 kPa for the prediction of cirrhosis, with a negative predictive value of 94%.
Conclusions LSM is useful for predicting hepatic fibrosis and excluding cirrhosis. A combination of LSM and US does not improve the accuracy
in assessing hepatic fibrosis. 相似文献

AIM: To assess the prevalence of the two mutations, C282Y and H63D of HFE gene, in healthy subjects, patients with chronic hepatitis C (CHC), and patients with nonalcoholic fatty liver disease (NAFLD) in Taiwan and to explore the contribution of the HFE mutation on serum iron stores in CHC and NAFLD groups. METHODS: We examined C282Y and H63D mutations of HFE gene in 125 healthy subjects, 29 patients with CHC, and 33 patients with NAFLD. The serum iron markers, including ferritin, iron, and total iron binding capacity (TIBC), were assessed in all patients. RESULTS: All of the healthy subjects and patients were free from C282Y mutation. The prevalence of H63D heter-ozygosity was 4/125 (3.20%) in healthy subjects, 2/29 (6.90%) in CHC group, and 1/33 (3.03%) in NAFLD group. The healthy subjects showed no significant difference in the prevalence of H63D mutation as compared with the CHC or NAFLD group. Increased serum iron store was found in 34.48% of CHC patients and 36.36% of NAFLD patients. In three patients of H63D heterozygosity, only one CHC patient had increased serum iron store. There was no significant difference in the prevalence of HFE mutations between patients with increased serum iron store and those without in CHC or NAFLD group. CONCLUSION: The HFE mutations may not contribute to iron accumulation in the CHC or NAFLD group even when serum iron overload is observed in more than one-third of these patients in Taiwan. 相似文献

乙型肝炎病毒基因型与病毒复制的关系 总被引:10,自引:1,他引:10
检测慢性乙型肝炎患者血清乙型肝炎病毒(HBV)基因型和病毒载量(HBV-DNA定量),探讨它们之间的关系。用微板核酸杂交-ELISA方法对HBV进行基因分型,用PCR荧光定量检测血清HBV-DNA水平,共318例。检测到HBV B型111例(35%);C型128(40%);混合型(B+C,C+D,B+C+D)45例(14%);D型2例;F型2例;未分型30例(9.4%);没有发现A、E型。结果发现,C型和混合型HBV的血清DNA水平高于B型(1.14×107vs2.2×107vsl.60×106拷贝/ml,P<0.05);而混合型HBV的血清DNA水平与C型无差别(P=0.127)。研究提示,我国HBV以B,C两基因型为主,HBV基因型可能是影响HBV复制的重要因素之一。 相似文献
